angular – 使用可注入服务来设置APP_BASE_HREF的配置

我使用以下代码创建了app-config服务：

import { Injectable } from '@angular/core';

@Injectable()
export class AppConfigService {
  public config: any = {
    auth0ApiKey: '<API_KEY>',auth0Domain: '<DOMAIN>',auth0CallbackUrl: '<CALLBACK_URL>',appBaseHref: '/'
  }

  constructor() {}

  /* Allows you to update any of the values dynamically */
  set(k: string,v: any): void {
    this.config[k] = v;
  }

  /* Returns the entire config object or just one value if key is provided */
  get(k: string): any {
    return k ? this.config[k] : this.config;
  }
}

现在我想在app-module.ts上使用该可注入服务来设置APP_BASE_HREF提供程序.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';
import { AppComponent } from './app/app.component';
import { HelpComponent } from './help/help.component';
import { WelcomeComponent } from './welcome/welcome.component';
import {APP_BASE_HREF} from "@angular/common";
import { MaterialModule } from "@angular/material";
import { AUTH_PROVIDERS }      from "angular2-jwt";
import { RouterModule }  from "@angular/router";
import {AppConfigService} from "app-config.service";

const appConfigService = new AppConfigService();    

@NgModule({
  declarations: [
    AppComponent,HelpComponent,WelcomeComponent
  ],imports: [
    BrowserModule,FormsModule,HttpModule,MaterialModule.forRoot(),RouterModule.forRoot([
      { path: "",redirectTo:"welcome",pathMatch:"full"},{ path: "welcome",component: WelcomeComponent },{ path: "help",component: HelpComponent},{ path: "**",redirectTo:"welcome"}
    ])
  ],providers: [AUTH_PROVIDERS,{provide: APP_BASE_HREF,useValue:appConfigService.get('appBaseHref')}],bootstrap: [AppComponent]
})
export class AppModule {
}

所以在这里我将类启动到const并使用它.有没有一种方式注入凉爽和性感的方式？

例如,对于我的auth服务,我在构造函数中定义了它

constructor(@Inject(AppConfigService) appConfigService:AppConfigService)

还有办法在这里做一件性感的事吗？或者只是按原样离开？

谢谢
